70 Quincy Vacuum Pump-QSV Series

Options

5.1 Energy recovery unit

Description

A large part of the energy required for any compression process is transformed into heat. For QSV oil-
injected screw vacuum pump, the major part of the compression heat is dissipated through the oil system.
The Quincy energy recovery (ER) systems are designed to recover most of the above-mentioned heat by
transforming it into warm or hot water without any adverse influence on the vacuum performance. The
water can be used for diverse applications.

Components

NOTICE!

When the option energy recovery is installed, the vacuum pumps shall be equipped with vacuum
synthetic fluid.

The energy recovery system is completely integrated and mainly comprises:



Oil / water heat exchanger (HE).



Elektronic thermostatic Valve for energy recovery heat exchanger (BV).



The necessary bolts, flexibles, etc.

Energy recovery unit (ER-unit)

Main components of the ER unit (typical installation)
